The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis's Swamp (沼泽地) creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack'sdare. They liked camping, but not near this swamp.

"So," Martin asked as they sat watching the hot coals. "How did this place get its name?"

"Are you sure you want to hear it? It's a scary story," warned Jack.

"Of course!" cried out Tom. "If there were anything to be scared of, you wouldn't have chosen this place!"

"Ok, but don't say I didn't warn you," said Jack, and he began this tale.

"Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in. In those days, the area looked quite different — it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice.

"‘You are clearing too much land,' warned one old man. ‘The land is a living thing. It will hit back at you if you abuse it. '"

"‘Silly fool,' said Dennis to himself. ‘If I clear more land, I can grow more crops. I'll become wealthier. He's just jealous!'"

"Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants."

"What happened?" Martin asked. It was growing colder. He trembled, twisting his body closer to the fire.

"The land hit back — just as the old man warned," Jack shrugged. "Dennis disappeared. Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found."

"What a stupid story," laughed Tom. "Plants can't …" Before he had finished speaking, he screamed and fainted (晕倒). The other two boys jumped up with fright, staring at Tom. Suddenly, they burst out laughing. Some green swamp ivy (常春藤) had covered Tom's face. It was a while before Tom could appreciate the joke.

"It's nice having a friend," said Mole (鼹鼠) to Rabbit as they sat talking in the sun one day.

"Oh, it is!" said Rabbit. "Very useful, too, 1 if you need help. 2 , I think I'd like Bull (公牛) to be my friend."

"But I'm your friend!" said Mole, feeling 3

"Oh, yes," said Rabbit. "You are good for talking to and laughing with, 4 you are too small. When I need help, I 5 someone big and strong like Bull. He would be a very good friend to have. It would be 6 shouting for him when I need help."

Mole went off in anger.

"Oh, well, I need to 7 something," Rabbit thought.

He moved along 8 he found a tiny garden. He had just started on his first leaf when there was a big noise. People were shouting and dogs were barking (吠叫). Rabbit was so afraid and in such a 9 to get away that he ran into the wrong hole. The hole was too small and Rabbit got stuck. He could not 10 at all.

"Help!" cried Rabbit.

Mole 11 him. He ran up to see what was the matter.

"Help!" cried Rabbit. "I'm stuck in this hole."

"If you want help," said Mole, "I'd better 12 Bull."

"No!" cried Rabbit. "He's no good! He's too big to get into this hole. You're just the right 13 ! Please help me, Mole!"

So Mole began digging around Rabbit. He worked so fast that Rabbit was 14 in no time.

"I'm sorry, Mole. I was wrong, " Rabbit said. "I'm 15 I have you as a friend."

And the two good friends set off for home together.

Chien-Shiung Wu was a Chinese-American particle and experimental physicist who made significant contributions in the fields of nuclear and particle physics. She is best known for conducting the Wu experiment, which proved that parity (对称) is not conserved. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in Physics, while Wu herself was awarded the Wolf Prize in Physics in 1978. Her expertise in experimental physics aroused comparisons to Marie Curie.

Chien-Shiung Wu was born in a town of Jiangsu province, China, in 1912. Wu and her father were extremely close, and he encouraged her interests passionately, creating an environment where she was surrounded by books, magazines, and newspapers. Wu received her elementary school education at Mingde Women's Vocational School founded by her father.

Wu left her hometown in 1923 to go to the Suzhou Women's Normal School No 2, which was fifty miles from her home. In an era when "getting married" was considered the best destiny for women, she carved out a new path for herself through her diligent and earnest approach to learning and her thirst for knowledge.

In 1936, Chien-Shiung Wu went to the United States to pursue further studies in atomic physics. It was during this period of her education that she came to know Oppenheimer, who was teaching in the Physics Department. Under the guidance of renowned physicists such as Oppenheimer, Lawrence, and Segre, Chien-Shiung, Wu successfully completed her studies and her doctoral research. Due to the highly sensitive nature of her work, the details of her research were not revealed until the end of World War II.

In 1984, Chien-Shiung Wu returned to China from the United States. At the age of 72, she made a substantial donation of $250,000 to her hometown to support its development. Later, she also became an academician of the Chinese Academy of Sciences.

In 1997, Chien-Shiung Wu passed away. Before her death, she requested to be buried in her hometown of Suzhou. Today, her tombstone in Taicang, Suzhou, bears the inscription: "She was an outstanding global citizen and a forever Chinese."

Juleus Ghunta is a published children's author and award-winning poet. But when young, he could 1 read.

He grew up with his three sisters in rural Western Jamaica, raised by their single mother. Life was tough, and proper schooling was out of the question due to 2 resources.

When Ghunta finally went to school, he couldn't 3 on reading. Not only had he been kept home from school as a child, but he had not been 4 to books.

By sixth grade, he could spell his name, but still couldn't make out words or read with 5 . He struggled in school with a deep sense of 6 and worthlessness.

At age 12, a young teacher-in-training 7 a special reading program for 8 students. Ghunta was the first to join. That teacher, whose name he does not 9 now, became Ghunta's unsung hero — the person who changed his life.

The teacher was incredibly kind to him. Under her guidance, Ghunta's reading skills saw marked improvement, and his sense of inadequacy began to 10 .

"She had left me with the gift of literacy," he said. "And a deeper 11 of my talent."

After Ghunta's experience with the teacher, his life course 12 . He graduated with academic 13 and is now the author of two children's books, including "Rohan Bullkin and the Shadows."

Years later, Ghunta returned to his old school and asked the principal and teachers if they knew her 14 , but none did. Carrying this memory, however, he still hopes to find and thank her for seeing his 15 and being a source of light and hope in his life.

The Aviation Industry Corporation of China (AVIC), China's leading aircraft maker, created the country's first fully solar-powered drone (无人机). The large drone, Qimingxing 50, took off at 5:50 pm on September 3rd, 2022, from an airport in Yulin of Shaanxi Province and stayed in the air for 26 minutes before landing on the same runway. AVIC said that all systems of the unmanned plane functioned well on its first flight.

Powered by six electric motors with solar batteries, the drone is designed to conduct long-time operations in near space. Near space is that part of Earth's atmosphere at altitudes of 20 to 100 kilometers. It is above the top altitudes of commercial airliners but below orbiting satellites.

Qimingxing 50, also called "quasi-satellite", features high operational efficiency and eco-friendliness and will be tasked with high-altitude reconnaissance (侦察), forestry fire monitoring, atmospheric environmental inspection, aerial mapping, communication signal relay and other operations.

"Thanks to its capability to conduct very long endurance flights in near space, the drone can essentially become a substitute for satellites," a Chinese aerospace expert said. Satellite services are not always available due to the limited number of satellites and relatively fixed schedules of overhead passes. In time-sensitive missions, near-space drones can offset these disadvantages, the expert said, noting that satellite services could also be damaged in wartime, so near-space drones could replace them in this occasion.

The successful first flight of the Qimingxing-50 lays a solid foundation for the development of key technologies in the country's new energy field, the composite (复合的) material field, which will enhance China's ability to perform tasks in near space and over far oceans. AVIC will seize the opportunity to increase investment and speed up the development of large solar-powered unmanned aircraft.

In a small town, there was a young man named Tom. Although he was just a(n) 1 person, Tom had a very kind heart and a strong sense of 2 . The town had a serious shortage of clean water. This problem had a big influence on the 3 . It messed up their usual activities and was a big threat to their health.

Tom, decided to do something. He spent a lot of time, working day and night to find possible solutions. He 4 different organizations and asked for their help. Many people around him thought it was a 5 thing and told him to stop. But Tom was very firm in his decision and always positive.

He 6 a group of people and they started a 7 to make people know how important clean water is. They gave out flyers all over the town and even went to every house to 8 the situation. Their efforts slowly started to work. People from all 9 of jobs in the town were 10 by their hard work and began to offer their help and resources.

With the efforts of the whole community, a new water 11 system was finally put in. The town now had clean and 12 water. Tom's action not only solved the water problem but also made the people closer to each other. It 13 that even an ordinary person can make a big difference in 14 if they are 15 and have a positive attitude.
